6 - Power protections
List
The Power protections, available by default for Ekip Hi-Touch, Ekip G Touch, Ekip G-Hi Touch models and configurable in Ekip Touch as additional
SW package, are:
Name Type of protection
RP Reverse active power
D Directional short-circuit with adjustable delay
(2)
OQ Maximum reactive power
(1)
OP Active overpower
(1)
UP Active underpower
(1)
RQ Reverse reactive power
(1)(2)
Cos φ Minimum Cos φ
Further details about the protections are given in document 1SDH001330R1002.
(1)
the protection is not available by default with Ekip Hi-Touch. However, it can be integrated by requesting the relative SW package
(2)
the protection is not available by default with Ekip G Touch. However, it can be integrated by requesting the relative SW package
(3)
Block configuration available via Ekip Connect
(4)
Directional Zone Selectivity functions as an alternative to Zone Selectivity S and G
WARNING! The Power flow parameters effect the sign of the power and power factor values measured by the unit.
Power flow must be configured and verified on the basis of your installation to ensure that all the protections of the
Power Protections package function correctly

calculation of t is valid for values which have exceeded the trip threshold of the protection
t
(6) tolerance values valid with Trip unit supplied at full rate or by auxiliary power supply, trip time ≥ 100 ms, temperature and current values within
operating limits; the tolerance value is ± 20% if the conditions are not guaranteed

ANSI / IEEE C37-2 codification
(8)
the protection does not detect the fault current direction for < 5 V voltages.
(9)
not active if the circuit-breaker is open (TRIP OFF is signaled); the protection is also active for negative active power, but is independent of RP
protection (Protection from inverse active power)
